' rotatably mounted in the irrigation ditch with its axle'extendin'g vertically, the water wheel being rotated by the. water passing through the ditch. t

Another object of the invention is to provide the water wheel with wire side walls through which thewater mayv freely pass7 but which will prevent the fish from passing through the ditch.

Another object of the invention is to provide the water wheel with an improved type of blade-supporting arms which are curved i longitudinally so that the blades will receive the greatest amount of action from the water and thus cause the water wheel to operate very efliciently.l

This invention is illustrated in the accompanying drawings wherein- Figure 1 is a transverse sectional view through the irrigating ditch with the water wheel shown in lside elevation, the Wire screening being partially removed; Fig. 2 is a top plan view of the waterwheel, the cross bar which carries a bearing for the upper end of the axle'being removed; Fig. 3 is a fragmentary sectional view showing a brush which cle'ans the wire walls of the water wheel. Fig. 4 is afragmentary view of the cross bar with the upper bearing in place.

The irrigating ditch isprovided with cement sides 10and a cement bottom 11 upon which there is mounted the lower bearing 12. The cross bar 13 is carried by the side walls 10 and extends transversely across the irrigating ditch. The striplll which is provided with a central bearing 15 is secured to the cross bar 13 by means of the bolts or other securing devices 16 and has itsupper edge portion engaged by the tongues .17 which extend downwardly from the plate 18. This plate 18 is secured to the `upper face of the cross bar by means of the bolts 19 or other securing devices and is provided `12 and 15. ditches, and the principal i of a Water wheel with acentral lip 20 which extends over' the i bearing 15 to form a cover for'the bearing.

The. water wheellO. rotatablyxmounted in the lrrlgatmg ditch 'has its hub 21 provided with anxaX-l 22 which/extends above and below the hub and v has upperand lower-end' portions rotatably-mounted' inthe bearings The spokes 234v which extend from the upper and lower' ends-of Athe hubA l are positioned alinement andare curved.-

as shown v1n Fig. 2, to allow thel greatest;v

amount of water pressureupon eachof the blades whlch are carried by the spokes. f The a outer ends of the spokes 23 are connectedby i the vertical standards 24 which havetheir of the lower spokes are secured.. A screen.- ing 25 which forms `the sidewalls-forthe water wheel 1s secured tol thebuter aces of the standards 24 and extends entirely around the water wheel so thatjiish will beprevent# ed from passing through the water wheel. The screen shown in the drawings has been sh'own with a relatively large mesh, but i-t -form to the curvature of the spokes 23 when in the operative position shown at the right' of F1g.2. The inner blades 2G have their pivot pins 28 rotatably connected lwith the -'l0 upper ends cut Hush with the upper spokes- 23 and have their lower'end portions'-ex:

tending below the lower spokes and provided with cut-out portions 24 in whichthe'ends vis obvious that the screen could vbe formed 'i spokes by means of the bearings 29 and the outer blades have their pivot pins 30 rotatably connected with the spokes by means oftheA bearings 31. The outer blades are of such length that when in the operative position shown in Fig. 2, their free ends will engage the pivot ends ofthe inner'blades 26 and the inner blades are of such height that when in the operative position the upper and lower edges of the inner blades will engage the upper and lower spokes. The outer blades may have their upper and lower edges engaging the spokes.

In the operation of this Adevice the water wheel is mounted as shown in Fig. 1 with the blades connected with the spokes upon the up-stream sides of the spokes as shown at Fig. 2 so that when the water passes through the irrigating ditch in the direction indicated by the arrow in this ligure, the Water will engage the blades upon the right hand side of the Water wheel and move them to a closed position. This provides asolid face for the Water to engage thus per mitting the Water to rotate the water Wheel. The blades upon the-opposite side of the Water Wheel Will. swing to the positions shown so that they will present comparatively no resistance to the position of the Water through the Water Wheel, thus permitting the Water wheel to turn freely. llt has been already pointed out in the body of the description that by having the spokes of the water Wheel curved as shown in Fig. 2 and having lbe blades curved to conform to the contour" the. spokes7 the AWater passing' through the irrigating ditch Will more readily rotate the water Wheel. lt Will thus be seen that While Water may pass through tlie irrigating ditch, fish will be prevented from' passing through the ditch due to the fact 'that the rotating Water Wheel Will prevent:

the passa'ge of the fish. lf it is desired to keep the screen Walls clean from mud or leaves, a brush 32 may be secured upon the stream side of 'the irrigating ditch to brush against the screen Walls and .thoroughly ren move any dirt or leaves. The Watery'vheel has been mounted with the axle extending vertically since by this arrangement the Water Wheel can be very easily mounted in the irrigating ditch, the bearing l2, and a bearing carried by the cross bar 13 being all that is necessary in order to rotatably mount the Water Wheel.

What is claimed is:

l. ln a fish stop a rotatably mounted. Water Wheel including a vertically-extending bottoni of said ditch, cross mariani hubj spokes extending from said hub, stan ards having their upper ends connected the outer ends of said upper spokes and h' ing their lower ends extending beneath lowery spokes and provided with cutout portions in which said lower spokes are cured, a perforated Wall carried by s standards and plates pivotally connec with said spokes.

2., ln an irrigating ditch a bearing i i bar extei a'ross said ditch, a plate secured to 'the s of said cross bar and provided intermedia its length with a bearing positioned above said first-mentioned bearing, a plate secured to the upper face of" said cross bar and vided with a lip extending above the beai secured 4thereon and being` also pro' with tongues extending to engage said s Cla n upon opposite sides of the bearing carried thereby, and a water Wheel mounted in said ditch and provided With a vertically-extending axle rotatably mounted in said-bearings.

3. A device oit' the character described in cliiding a lovver bearing,- an upper bar, bearing iitting against said barj a Water wheel positioned beneath said bar and pro vided with a vertically extendingn axle ro tatably mounted in said bearings, and a securing plate vfastened upon the upper face o; said bar and provided With 'tongues extending to engage the bearings carried by said bar to hold said bearings in place.
